TRACK.

SPECIFICATION forming part of Letters Patent No. 700,084, dated May 13, 1902.

' Application filed July 10,1901. Serial No. 67,719. (No model.)

To a whom, it may concern:

Be it known that I, JOHN B. QUINN, acitizen of the United States of America, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and usefulImprovements in Tracks, of which the following is a specification.

My invention relates to certain improvements in tracks, the object being to provide a track where it is desirable to use a double track, but where economy of space is desired. This track has been thus far employed successfully on apparatus for filling in embankments, &c., where it is desirable to run a car filled with dirt, stone, or the like out upon one side until sufiicient material has been deposited and then to run it upon the other side without separating too much the points at which the cars are discharged.

To such end the invention consists in certain novel characteristics, a description of which will be found in the following specification and the essential features pointed out in the claims.

In the drawings presented herewith, Figure 1 is a plan view of the track, showing the arrangement thereof; and Fig. 2 is a perspective view of a curved section of a piece of rail.

In the views, A represents the two rails of the straight track, and B the rails running to a siding, the two running together at a and there provided witha switch of the ordinary form. Beyond the switch at a, is a second switch I), dividing the track into a Y or two ways C D, a single rail 0 being employed in the middle and tworails c d lying on opposite sides thereof and equidistant therefrom, thus forming a double track, with the rail 0 used in common with both. The double track C D may of course extend to any suitable length and is connected to the main track A by the switch b, which consists of two moving switch-points 19 6 each converging toward the middle rail 0. The rails of the track A at the switch-points diverge from the switch-points out to the outer rails c d of the double track, asindicated in Fig. 1. The switch-points stop short of the middle rail 0, and a connecting rail-section c is interposed between one of them and said middle rail. This rail-section c is of the proper curve to conform to the curve between the diverging rails a a and the outside rails c d and may be disconnected from either switch-point and turned around and connected to the other, so as to permit the cars to be switched. from the main track to either section of the Y.

I claim as new and desire to secure by Letters Patent 1. In a track system, the combination with two parallel rails forming a portion of a single track, of three parallel rails a short distance therefrom, the middle rail of which is adapted for use with either of the outer rails, and connecting-rails-between both rails of the single track and the middle of thev three rails, the connecting-rails between the single track and the middle rail being provided with means whereby they may be brought alternately into 7 use to connect the single track with either side of the three-rail track; substantially as described.

2. In a track system, the combination with two parallel rails separated to the extent of the track-gage and having diverging extensions, separating to substantially twice said gage and thereafter extending in parallel directions, of a third rail between the latter parallel portions and equidistant therefrom, and movable connections between said middle rail and each of the former parallel portions of thetwo rails, said movable portions being capable of alternate movement toward their respective side rails to connect the latter with the middle rail; substantially as described.

8. The combination with a two-rail track, of a double three-rail track formed by a continuation of the rails of the two-rail track, diverging to twice the distance and a third rail intermediate and equidistant therefrom,

a pair of split-point switch-rails, moving alternately into'engagement with the rails of the two-rail track and leading therefrom toward the middle rail and a bent reversible connecting portion adapted, when placed in the proper position, to connect either ofthe switch-rails with the middle rai l;.substantially as described.

In witness whereof I have hereunto set my hand, at Chicago, in the county of Cook and State of Illinois, this 8th day of July, A. D. 1901. v
